What if there is no iron in this Universe?
"Iron" is a strange but important thing in this Universe, or this planet.
If there is no iron, it means there will be no electricity.
If there is no electricity, it means human will not be developing so fast.
Electricity is coming from a strange magnetic design of a motor.
Electricity comes from a circular motion from the motor. It is the magnetic effect of iron.
If there is no iron at all, then there will be no electricity.
Maybe future scientists can invent some other kind of electricity without using iron. Actually, it deserves a try. If you can push something dancing or circling like a ballerina, then you might have invented another kind of motor without electricity.
May be the study of inertia can help. Clever people can use inertia to replace electricity.
However, it is still a puzzle for us: What if we have no iron and no electricity?
What if the industrial revolution had never happened?
Can you believe that something is pushing humans going?
If there is no iron at all on this planet, we will be going back to the times before industrial revolution.
Maybe there will be no Opium War in 1842.
However, it is only a joke. Don't worry.
